for booleans, "is" is a valid prefix. Try
<c:if test="{sessionScope.user.admin}">
XYZ
</c:if>
the prefix is removes as per the java beans specification

Subject: Custom tag, JSTL tag or Other for bean.isXXX() call?
Hi All
I am running a Struts-based intranet web application. Each user has a
session object called IQUser loaded. One of the methods of this object is
hasRole(String roleKey). Another is isAdmin() which calls hasRole("admin").
I wish to clean the JSP scriplet code I have everywhere ...
<%
if (user.hasRole("admin")) { %>
XYZ
<%
}
%>
with tag library calls. My first thought was that I need to create a custom
tag
<iq:hasRole role="admin">
XYZ
</iq:hasRole>
Then I thought why not try to use JSTL, so I tried
<c:id test="{sessionScope.user.isAdmin}">
XYZ
</c:if>
to find that it did not work, and looking at references it seems that JSTL
cannot do method calls unless they are getXXX.
I do not want to set isAdmin as a boolean in some scope so that the
following works
<c:id test="{requestScope.isAdmin}">
XYZ
</c:if>
because I find that messy when the user object exists in the session
already.
It looks like I may have to go back to my original idea of a custom tag, but
I wanted to see what this list recommended first...I thought this would be
straightforward since calling boolean methods in beans with isXXX or hasXXX
is as widespread as getXXX.
Cheers, ADC
